Specification of Letters Patent.

Application filed April 21,1917. Serial no. 163,596.-

-To all whom it may concern in the county of Mobile and Stateo f A.la'

bama, have invented certain new and use ful Improvements'inSyrup-Evaporators, of which the following is a specification.

My present invention has to do with syrup evaporators. It consists inthe peculiar construction, novel combination and adaptation and relativearrangement of parts, as hereinafter described and claimed, wherebytheevaporator is provided with a solid, durable and liquid-tight bottomwall, and the transverse partition walls are fixedly attached to saidbottom wall and strongly maintained in position without the employmentof solder or any other element liable to be affected by fire or heat.

In the accompanying drawings which are hereby made a part hereof:

Figure l is a longitudinal vertical section illustrating the evaporatorconstituting the best practical embodiment of my invention that I haveas yet devised.

Fig. 2 is a plan view of the same.

Fig. 3 is a. perspective, on an enlarged scale, showing the relativearrangement of the bottom wall and one partition wall precedent to theapplication of pressure to clamp the engaged parts of said walls and fixthe same with respect to each other.

Fig. 4 is an enlarged detail section showing the bottom wall and onepartition wall as they appear subsequently to the application ofpressure and the fixing of the partition wall to the bottom wall.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

As shown in Figs. 1 and 2 ,my novel evaporator comprises, among otherparts, two upright wooden side walls 1 and 2. These side walls 1 and 2are arranged in parallel relation, and the wall 1 is provided,.adjacentto one of its ends, with a transverse outlet aperture 3 for thedischarge of syrup from the evaporator.

Embedded along its side edges in the opposed side walls 1 and 2 is thesheet metal bottom wall 4, and carried by the said bottom wall 4 andeach embedded at one end in one wooden side wall are the comparativelyhigh transverse partition walls 5 and the low or shallow transversepartition walls 6. These walls 5 and 6 are alternately secured toopposite side walls, each wall 5 and 6 extending from one side wall andhaving its free end spaced from the other side wall in order to causethesyrup to, take a tortu one course in passing from the right-hand end ofthe evaporator toward the discharge outletbefore'referred to, asindicated by the arrows in "F ig.' 2. Aside from difi'erences in heightthe transverse partition walls 5' and 6 are identical in constructionand are similarly fixed withrespect to the bottom wall 4, and thereforea detailed description of the wall 5 and the adjacent portion of thewall 4 shown in Figs. 3 and 4 will suffice to impart a definiteunderstanding of all.

For the reception of the said wall 5, the bottom wall 4 is provided withthe opposite folds 7 and the throat 8 between the folds. The wall 5 isformed of a sheet of metal bent on itself to constitute an upstandingportion, and the said sheet of metal is provided at the base of theupstanding portions with flanges 9. These flanges 9 are sheathed,preferably by endwise movement of the wall 5, in the folds 7 and thebase of the upstandportion is disposed in the throat 8. The opposedportions of the folds 7 and the flanges 9 are then subjected to pressureto tightly clamp the flanges between the folds whereupon the partitionwall will be fixed in and to the bottom wall and a liquid tight jointwill be provided between thetwo, and this without the employment ofsolder or any other extraneous means.

It will be observed in this connection that the upstanding portion ofthe wall 5 is strongly clamped and held between the upper opposed bightsof the folds 7, and the said wall 5 is effectually held at both sidesthereof against movement in the direction of its thickness; also, thatthe sheathing capacity of the folds 7 permits of the wall 5 beingexpeditiously and easily positioned, relative to the bottom wall beforethe opposed portions of the folds 7 and flanges 9 are subjected topressure as described.

In assembling the parts of my novel evaporator, the end portionsof thebottom wall 4 are bent upwardly to form end walls 10, the upper edges ofwhich are beaded as in: dicated by 11, and the side edges of the bottomwall, throughout the length thereof are tightly seated in groovesprovided in the in,- ner sides of the side walls, while one end ofPatented an. 1, 1918.

each transverse Wall is tightly seated in other and thisgalsocontributes-materially to the simplicity, inexpensiveness and durabilityof the evaporator.

Having described my invention, What I claim and desire to secure byLetters Patent is: V v e V In an evaporator, the combination of asheet-metal bottom' all having at intervals of its length pairs ofopposite folds and a throat between the folds of each pair, andtransversepartition Walls carried by the bottom Wall, each of saidpartition alls being formed of a single piece of sheet-metal foldeduponitself to form an upstanding po tio and eac ha ng ppos tely a hi giand'the base flanges of the partition Walls beingclamped together,Whereby'the up-g standlng portions of the partition Walls are stronglyclamped and held between the upper opposed bightsof the bottom Wallfolds and the partition Walls are held at both sides thereof against.movement in the direction of the lengthofthe bottom Wall. V

In testimony whereof I affix my signaturein presence of tWo Witnesses. p
